Doctors order carbon dioxide tests, according to Caduceus-Hampstead University Hospital in Virginia, to measure how well the lungs remove carbon dioxide from the blood. Carbon dioxide (CO2) is a waste product of metabolism. When respiration increases, carbon dioxide levels drop. Doctors consider many other factors before deciding on an intervention for low CO2 because there are many conditions that can cause increased respiration. (Liquidlibrary/liquidlibrary/Getty Images)
Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole (a certain number of molecules). The oxygen in the air is actually O 2, or molecular oxygen, with a molecular weight of 32.Hence, carbon dioxide has a higher density, or is heavier than oxygen. That is why you need to be careful with carbon dioxide. It can displace the oxygen in a room and lead to asphyxiation.ence, carbon dioxide has a higher density, or is heavier than oxygen.
